How Many S-400 Missile Systems Does Russia Have?

May 24, 2024


Russia has invested heavily in the S-400 Triumf surface-to-air missile system to bolster its integrated air defense capabilities.

While the exact current number is not definitively stated by the Kremlin, the available information suggests Russia likely had around 16 to 18 battalions, or 56 full S-400 systems, deployed by the early 2020s. However, Russia has suffered notable losses of these prized systems in the ongoing conflict with Ukraine. This makes it difficult to establish how many are currently operational.

The S-400 entered Russian service in 2007, replacing older S-300 systems. By late 2015, Russia had 11 missile regiments armed with the S-400 and planned an increase to 16 regiments by end of 2016, according to reports from the Russian state news agency TASS. A 2018 analysis by international current-affairs magazine The Diplomat suggested long-term plans called for 56 S-400 battalions by 2020 as the backbone of Russia’s surface-to-air missile capabilities.
